Anchor Coins are a large class of assets that anchor their price to a certain target through various mechanisms. For example, USDT, USDC, BUSD, DAI are all anchored to USD; WBTC, RENBTC are all anchored to Bitcoin. The prices between similarly anchored coins are very stable and usually stay around 1. If a curve can be defined that concentrates liquidity at price 1, which fits the anchor coin market pattern, it can provide very sufficient liquidity support.
